Patented lll/lay 2, 1916..

To all whom t may concern Be it `known that we, HERMAN C. OsMoND, J r., and AXEL PETERSON, respectively a `citizen of the United States and a subject of the King of Sweden, both residing in Philadelphia, Pennsylvania, have invented cer-` tain Improvements in Doors, of which the following is a specification.

Our invention relates to a door of that l@ type at present in use for closing the front of a telephone booth, closet, or like compartment, and comprising two' wings having a hinge connection at thgir adjoining edges with an interposed post, one of said wings being hinged to the front of the booth so as to swing into the same, carrying with it the other wing and the interposed post, so that said other wing can be folded side by side with the first and will thus occupy but a limited amount of space within the booth.

The object of our invention is Yto so construct the connection between the opposite wings and the interposed post that when 2a outward pressure is exerted by the hand against the inner face of said post there will be no possibility of the hand being caught between the adjoining edges of the swinging wings of the door. ln the accompanying drawings Figure 1 is a front view of a telephone booth having aA door constructed in accordance with our invention; Fig. 2 is a horizontal section ofthe casing of the booth on a larger scale 'than Fig. 1, showing in full lines a top view of the door in closed position and in dotted lines a like view of the door in a folded orV open position; Fig. 3 is a top view of the central portion of the door on a larger scale au than Fig. 2 and with the wings of the door in line with one another as when the door is closed; Fig. 4 is a similar view showing one wing folded against the other as whenthe door is open; Fig. 5 is a transverse section a on the line ze-a, Fig.v 3, with certain pivot pins shown in side elevation; Fig.v 6 is a view, partly in horizontal section and partly in top view, of a central hinge structure of the door with the wings in line with one ane 5o lother; Fig. 7 is a similar view showing the wings folded against one another; Fig. 8 is a transverse section Aon the line 6 6, Fig. 6, and Fig. 9 is a section on the line c-c, Fig. 6.

The improved door comprises a central post 1 extending from top to bottom of the door, and right and left hand wings 2 and 3 hinged to said post at their adjoining edges, the wing 2 being also hinged to the front of the casing a: of the booth by means of a hinge Ll, as shown in Fig. 2, so that in order to gain access to the booth the cential post l of the door can be moved from the position shown by full lines in Fig. 2 to'that shown by dotted lines in said figure, the wing 2 of the door swinging inwardly into the booth and the wing 3 being folded back upon the wing 2 so that the door will occupy the minimum amount of space on the inside of the booth.

The wings 2 and 3 are hinged to the central post 1 of the door at thetop, bottom and center of the latter, the top and bottom hinge plates 5 being secured, respectively, to the top and bottom of the post l by means of screws 6v or other available fastenings, and having downwardly projecting pintles 7 which enter openings in the top or bottom faces of the wings 2 and 3, respectively, as shown for instance in Fig. 5.

The hinge plates 5 project laterally in both directions beyond the central post 1 and are contained within recesses formed in the upperor lower faces of the wings 2 and 3, the inner or adjoining faces of said wings having a convex contour extending `from top to bottom of the same and concentric with the. axes of the pintles 7. The right and left hand faces of the central post 1 present a concave contour extending from top to bottom and likewise concentric with the axes of the hinge pintles 7 so that no gaps will be formed between the central post and side wings in swinging from the position shown in Fig. 3 to that shown in Fig. 4.

Theouter faces of the hinge plates 5 and the adjoining walls of the recesses formed inthe upper or lower faces of the wings 2 and 3 for the reception of said hinge plates are also concentric with the axes of the pintles 7, as shown in Fig. 3.

The central hinge structure of the door comprises a hinge plate 8 let into a recess in one face of the post 1 and projecting laterally on each side of said post, as shown at 8";L in Figs. 6 and 7, said hinge plate 8 also having a vertical face plate 8b which is secured to the corresponding facel of the post 1, as shown in Fig. 9.

Secured tothe inner face of each of the wings 2 and 3 of the door above and below t the hinge plate 8 is a right angled bracket plate 9, which bracket plates are pivotally connected to `the hinge plate 8 b y means of vertical pintles V10, as shown in Fig. 8, the projecting side members 8 of the hinge plate 8 and the corresponding bracket plates 9 being adapted to recesses 11 formed in the inner faces of the wings 2 and 3, as shown in Fig. 8.

The axes of the pintles 10 are coincident with the axes of the upper and lower pintles 7 and the outer faces of the side members 8 of the hinge plate 8 and the adjoining walls of the recesses 11 are coincident with the said axes so as to avoid the formation of wide gaps between them as the wings 2 and 3 swing from the position shown in Fig. 6 to that shown in Fig. 7

The provision of the central post l extending from top to bottom of the door and having top and bottomV and central hinge connection witlithe opposite side wings of the door insures the strength and rigidity of the. door structure as a whole, while yet permitting free swinging movement of the parts of the door in respect to one another upon yaxes coincident with those of the hinge pintles, thereby permitting free opening and closing movements of the door without risk of loosening of the hinge connections by reason of any rough handling to which the door may be subjected in use.

The outer edges of the wings 2 and 3 of thejdoor are rabbeted, as shown in Fig. 2, so as to overlap the adjacent edges of the door frame when the door is closed, as shown in Fig. 2, the edge of the wing 2 swinging away Y from the corresponding edge of the, door frame as said wing 2 movement of the post 1 at the same time causing the outer edge of the wing 3 of the door to be drawn inwardly away from the adjoining edge of the door frame, hence while the door when closed may be said to have a sound proof joint with the door frame, the free opening and closing of the door is not interfered with.

In closing a dooil of the type to which my invention relates it is customary to press outwardly'uponvthe inner face of the central. post l as the door approaches the closing position so as vto vstraighten the toggle formed by the wings and post, and thus press the outer face of the wing 3 firmly against the jainb x of the doorway. Wien the post l is constructed so as to overlap the adjoining edges of the wings 2 and 3 of the door it permits such outward pressure to bei safely impart-ed to it by the hand. whereas if the adjoining edges of the wings overlap the post the overlapping portions approach each other as the door closes and swings inwardly on. its hinge 4l, and the inward swinging prevent such safe use of the hand for imparting outward pressure to the post.

Ve claim:

1. The combination, in a door for telephone booths or like structures, of a central vertical post having a concave recess in each side of the same, and right and left hand wings hinged to said post, the adjoining faces of said wings being convex, and said convex faces and the corresponding concave faces of the post being` concentric with the axes of the hinge pintles.

2. The combination, in a door for telephone booths or the like, of a central post having a concave recess at each side of the same, right and left hand wings hinged to said post and having convex faces fitted to the concave faces of the post, hinge plates secui'ed to said post and having opposite side members projecting laterally beyond the concave faces of the post, and hinge pintles carried by said oppositely projecting side members.

3. rIhe combination, in a door for telephone booths or the like, of a central post having a concave recess in each side of the same, opposite side wings having convex faces fitted to said concave recesses, a hing plate let into said post and projecting laterally into the concave recesses of the same, pintles projecting vertically from said laterally projecting portions of the hinge plate, and right angled bracket plates each having one member secured to the convex face of a door wing and the other member with opening therein for receiving said pintle.

4L. The combination, in a door for telephone booths oi the like, of a central post having a concave recess in each side of the saine, opposite side wingshaving convex faces fitted to said concave recesses, a hinge plate let into said post and projecting laterally into the concave recesses of the same, pintles projecting vertically above and below said laterally projecting portions of the hinge plate, and right angled brackets secured to the door wings above and below said hinge plate, each of said brackets having one member secured to the concave face lll) of the door wing and the other member with opening therein for the reception of the hinge pintle.

In testimony whereof. we have signed our names to' this specification, in the presence of two subscribing witnesses.
